Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Time-of-check Time-of-use (TOCTOU) Race Condition
EUVDB-ID: #VU79522
Risk: Low
CVSSv3.1: 6.4 [CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-35937
CWE-ID:
CWE-367 - Time-of-check Time-of-use (TOCTOU) Race Condition
Exploit availability: No
DescriptionThe vulnerability allows a local privileged user to escalate privileges on the system.
The vulnerability exist due to race condition. A local privileged user can bypass the checks that were introduced in response to CVE-2017-7500 and CVE-2017-7501, potentially gaining root privileges.

EUVDB-ID: #VU31245
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7500
CWE-ID:
CWE-59 - Improper Link Resolution Before File Access ('Link Following')
Exploit availability: No
DescriptionThe vulnerability allows a local authenticated user to execute arbitrary code.
It was found that rpm did not properly handle RPM installations when a destination path was a symbolic link to a directory, possibly changing ownership and permissions of an arbitrary directory, and RPM files being placed in an arbitrary destination. An attacker, with write access to a directory in which a subdirectory will be installed, could redirect that directory to an arbitrary location and gain root privilege.

EUVDB-ID: #VU31396
Risk: Low
CVSSv3.1: 6.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7501
CWE-ID:
CWE-59 - Improper Link Resolution Before File Access ('Link Following')
Exploit availability: No
DescriptionThe vulnerability allows a local authenticated user to execute arbitrary code.
It was found that versions of rpm before 4.13.0.2 use temporary files with predictable names when installing an RPM. An attacker with ability to write in a directory where files will be installed could create symbolic links to an arbitrary location and modify content, and possibly permissions to arbitrary files, which could be used for denial of service or possibly privilege escalation.
